Hey Brent,
Thank you very much for investigating on this.
The confusing thing is, the same script returned proper result but the next day broken.
Also, as suggested, I redownload the newest lib, regenerate the four keys(token) and run analytics.php again, I got “NOT_AUTHORIZED” error message.
Can u pls let me know is anything wrong on my side? Is it app access privilege issue?
Any questions please let me know. Thanks.
